确定网络标志中的最大、最小和平均海龟集群大小以及海龟集群的数量。

Question

请参阅下面的代码，用于确定一些随机分布的未定居海龟(黑色)中的定居海龟群(红海龟和灰海龟)的数量，以及网络标识世界/界面中的最大、最小和平均集群大小(径向范围)。

globals[ cluster-size cluster-count cluster-size-growth cluster-count-growth ]

to setup
  clear-all
  ask patches [ set pcolor white ]
  create-turtles 1000 [
    set color black
    set label-color blue
    setxy random-xcor random-ycor
    set cluster-size 1
  ]
  ask n-of 5 turtles [
    ask turtles in-radius one-of [1 2 3] [
      set color one-of [red grey]
    ]
  ]
end

to cluster-collect
  let base-settlers turtles with [ color = red ]
  let consp-settlers turtles with [ color = grey ]
  ask base-settlers [
    set cluster-count count consp-settlers in-radius cluster-size
    set cluster-size-growth cluster-size + 1
    set cluster-count-growth count consp-settlers in-radius cluster-size-growth
    if cluster-count >= 1 [
      ifelse ( cluster-count-growth - cluster-count != 0 ) [
        set cluster-size cluster-size + 1
      ][
        print count base-settlers with [ count turtles with [ color = grey ] >=  1 ]
      ]
    ]
  ]
  print [ max cluster-size-growth ] of base-settlers
  print [ max cluster-count-growth ] of base-settlers
  print [ mean cluster-size-growth ] of base-settlers
  print [ mean cluster-count-growth ] of base-settlers
  print [ min cluster-size-growth ] of base-settlers
  print [ min cluster-count-growth ] of base-settlers
  print [ standard-deviation cluster-size-growth ] of base-settlers
  print [ standard-deviation cluster-count-growth ] of base-settlers
  print [ variance cluster-size-growth ] of base-settlers
  print [ variance cluster-count-growth ] of base-settlers
end

我得到的错误如下：MAX expected input to be a list but got the number 10 instead.，我敢打赌，它也会对均值和最小函数做同样的操作，因为它没有将基本定居者识别为一个代理集。对于如何转换此代码以获得最大、最小和平均集群大小(径向范围)和固定海龟数量(红色和灰色)，有什么想法吗？

Answer 1

运行代码时，NetLogo突出显示生成错误的行。问题线是print max cluster-size-growth。如果您更早地查看，那么在此之前有let cluster-size-growth cluster-size + 1和let cluster-size 1。所以cluster-size-growth是1+ 1，或者是数字2，变量cluster-count-growth也是一个数字。

我想(但我不确定)，你正试图为每只海龟计算这两个变量，然后取相同类型的海龟的最大/平均/分。如果是这样的话，您需要首先为所有海龟创建变量(即结束ask []语句)，然后执行类似于print max cluster-size-growth of base-settlers的操作。您还可能需要为这些变量建立turtle-own变量，因为局部变量值将在ask []块的末尾丢失。
